RHBA-2020:1297 - Bug Fix Advisory

Topic

Updated director installer packages that resolve various issues are now
available for Red Hat OpenStack Platform 13.0 (Queens) for RHEL 7.

Description

Red Hat OpenStack Platform provides the facilities for building, deploying
and monitoring a private or public infrastructure-as-a-service (IaaS) cloud
running on commonly available physical hardware.

Changes to the openstack-tripleo-heat-templates component:

• Before this update, when upgrading Red Hat OpenStack Platform (RHOSP) 13 on 64-bit PowerPC processors to the latest maintenance release, Paunch would fail to create the `nova_libvirt` container, report the following error, and cause the upgrade to fail:

/usr/bin/docker-current: Error response from daemon:
Requested CPUs are not available….

The value of the RHOSP parameter, `cpuset_cpus`, in nova-libvirt.yaml defaults to all CPUs. In cases where the simultaneous multithreading (SMT) control was disabled, the CPUs were exposed differently and the RHOSP upgrade was failing.

Two changes have been made to resolve this issue. First, by default, Docker automatically determines for you which CPUs are available. The second change is that you can use a new role-based parameter, `ContainerCpusetCpus` to override Docker. For more information, see https://access.redhat.com/solutions/4917021. (BZ#1813091)

Solution

Before applying this update, ensure all previously released errata relevant
to your system have been applied.
